MAINTENANCEFinal setting of the idling speed TAdjust the idling speed withthe screw T, if it is necessaryto readjust. First turn theidle speed adjusting screw Tclockwise until the cuttingattachment starts to rotate/move.Then turn, counter-clock-wise until the cuttingattachment stops, a corre.ctlyadjusted idle speed settingoccm_ when the engine runssmoothly in every position.It should also be goodmargin to the rpm when thecutting attachment starts torotate/move.CAUTION! Contact your setwicing dealer, if the idle speedsetting cannot be adjusted so that the cutting attachmentstops. Do not use the machine until it has been properlyadjusted or repaired.High speed needleHThe high speed needleaffects the machine's power,speed, temperature, and fuelconsumption, a too leanadjustment on the highspeed needle H (the highspeed needle H is screwed intoo much) gives a too highspeed resulting in enginedamage. Do not allow theengine to run at full speedfor more than 10 seconds.Apply full throttle and turnthe high speed needle Hslowly anticlockwise untilthe engine runs unevenly.The high speed needle H isthen turned slowlyclockwise a little until theengine runs smoothly.Note the engine should berun unloaded whenadjusting the high speedneedle.Therefore dismantle the cutting equipment, nut, supportflange and disc drive before adjusting the high speed needle.The high speed needle is adjusted correctly when the machine'splatters' a little. If the machine smokes heavily at the sametime as it 'splatters' heavily the adjustment is too rich.NOTE! For optimum setting of the carburetor, contact aqualified servicing dealer who has a revolution counter at hisdisposal.Correctly adjusted carburetorA correctly adjusted carburetor means that the machineaccelerates without hesitation and the machine 4-cyclas a littleat max speed. Furthermore, the cutting attachment must notrotate/move at idling. A too lean adjusted low speed needle Lmay cause starting difficulties and bad acceleration.A too lean adjusted high speed needle H gives lower power =less capacity, bad acceleration and/or damage to the engine.A too rich adjustment of the two speed needles L and H givesacceleration problems or too low working speed.18- English
